In accordance with the resent invention there is produced a bath tuhaving a rim 2, from both ends and one side of which a reinn forclng,water-restraining 4 and anchorin flange 3 projects upwardly. Adjacenteac end of the tub there is formed a pedestal 4, extending downwardlyfrom the rimand ofiset with respect to the main body of the'tub, to

as clearly indicated in Figure 1 of the drawlngs.

A tub of the general construction referred to may be formed either ofcast metal or of sheet metal, and is herein termed, for sake ofconvenience, a single shell tub.

Due to the many advantages inherent in properly constructed sheet metaltubs, I refer to manufacture my improved tub of s eet metal, andpreferably of sections secured together by'welding, whereby all deepdrawing operations, together with the strains incidental thereto, areeliminated.

In accordance with the preferred method of carrying out the presentinvention, I.uti-

lize a substantially rectangular sheet of metal of the requireddimensions, indicated generally in Figure 5 of the drawings, and punchtherefrom a bottom forming section 5, as illustrated in Figure 6,thereby leaving a rim forming section 6 in the form of a continuous bandor annulus. The rim forming section is then subjected to suitable diestov a shaping operation to provide the upstanding flange 3 thereon andto form a downturned edge 7 continuously around the punched opening. Atthe same time, the Widen side 8 of the rim section is shaped to providedownturned end portions 9, as clearly indicated in Figure 2, and anintermediate downwardly and inwardly turned portion 10. The blank, afterthe shaping thereof, is illustrated in perspective in Figure 2 of thedrawings.

To form the main body of the tub, I may utilize a body forming section11, as illustrated in plan in Figure 14 of the drawings and shape thesame around a suitable former, in any desired manner, to impart theretothe general contour illustrated in Figure 3.

estal and-body forming section, as illustrated in Figure 4 of thedrawings, such section having offset pedestal portions 12 thereon, eachprovided with an inturned reinforcing and supporting flange 13 at thelower edge. I

Intermediate the pedestal forming portions 12, the blank is offset toprovide a portion 14, adapted to constitute a continuation of the mainbody section 11, as illustrated in Figure 4, and shaped to provide asupporting portion 15. i

The bottom forming blank 5 removed by the punching operation, is thenshaped in any desired manner, to form the bottom section 16 of Figures-7and 8. Due to the relatively smaller dimension of the bottom of a bath.tub, the section punched from the rim forming section providessufficient metal for the construction of the bottom. After the foursections above described have been completed, they are assembled intothe shape illustrated in Figure 1, in which positionthe bottom 16 abutsthe bottom edge 17 on the body forming section 11, and the offsetportion 18 on the pedestal and bottom forming section along a lineextending substantially circumferentially of the top. The rim formingsection 6 likewise abuts the sections referred to along their upperedges and along a substantially circumferentially extending line, lyingin a plane generally parallel to the line first referred to. The ends18. of the body forming section abut against the shoulders 19 of thecombined pedestal and body forming section and constitute a continuationof the portion. 14 of such section. I I

These arts may conveniently be secured together hy welding along thecircumferentially extending lines and along the ends of the body formingsection. The downturned edges 9 of the top section also abut against theupper edges 20 of the pedestal forming sections to'which they may bewelded.

From the foregoing it will be apparent that I may form a complete tubfrom a series of easily produced sheet metal sections comprising a topsection, a bottomv section, a

main body section,.and acombined pedestal and body forming section. thebottom section of which is formed by the metal removed from the topsection. The utilization of a single section for forming the front ofthe tub and the pedestals-provides a tub of single shell construction,thereby greatly decreasing the weight of the finished article. Thisadvantage is obtained in' the manufacture of a sheet metal tub or a castmetal tub.

In the completed tub, the pedestal portions 4 impart'a distinctive andattractive appearance in addition to cooperatin 'with thewalls of theroom in which the tub is placed.

flange3 onthe top section is adapted to ex-- tend into, and to interlockwith, a wall 21, thereby preventing movement of the tub relatively tothe. wall, and also providing such an abrupt change of section as toprevent the passage of water over the tub either by capillary attractionor under the influence of gravity.

While I have herein illustrated a preferred construction and a preferredmethod of making the same, it will be understood that changes in theconstruction and contour may be made without departing either from thespirit ofmy invention or the scope of my broader claims.
